[Touch-packages] [Bug 1826648] Re: cupds crashes with core dump
August Rydberg (august-rydberg), if you are using Focal, the cups- browsed crash is possibly caused by bug 1857815. Please follow the instructions I have given there for a debug log of cups-browsed, but please post your answer there, not in this bug report. If you are not using Focal, your bug seems to be something different and most probably not the bug which was reported here originally.

[Touch-packages] [Bug 1826648] Re: cupds crashes with core dump
I have the same problems as described in this bug. Every time I print something cupsd crashes with core dump and cups-browsed also crashes. My printer is a Samsung CLX 6260 Series. I can successfully print one job, then get the crash, then have to wait some minutes before the services are up again, and so on. I found out that if I stop the cups-browsed service the problem goes away. This is fine for me as I've already added my printer manually and I don't need to automatically find new printers. For some odd reason, another copy of my printer is added even though the service was disabled. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1826648 Title: cupds crashes with core dump Status in cups package in Ubuntu: Expired Bug description: At home my cupsd daemon crashes all the time.
